HANGER FOR RAILS Filed Aug. 6 1931 Ami'Tmn/F V Min 2v I? 22 6' 22 21 I9 Patented Feb. 23, 1932 UNITED STATES PATENT OFFICE LLOYD R. BERGREN, OF FAIRFIELD, IOWA, ASSIGNOR TO THE LOUDELT MACHINERY COMPANY, OF FAIRFIELD, IOWA, A. CORPORATION OF IOWA HANGER FOR RAILS Application filed August 6, 1931. Serial No. 555,471.

used for suspending rails for any purpose and is especially useful for suspending rails provided with flanges on the opposite sides of the web, the lower set of flanges forming trackways for trolleys bearing loads to pass along.

.1 Oftentimes the distance between the supporting member and the rail is limited because of low ceilings or for other reasons and in instances of this kind, a hanger requiring but a small amount of space between the rail and its support, or head room as it is called, is necessary.

The object of the invention is to provide a hanger having hooks to engage the upper flanges of the rail wherein the bending moment of the hooks is eliminated.

Another object of the invention is to provide a hanger requiring but a small amount of head-room.

The above and other objects and advann; tages will appear from a consideration of the following description in conjunction with the accompanying drawings in which Fig. 1 is an end elevation showing a rail secured to a support by means of my hanger, the rail being set at a right angle to the sup port.

Fig. 2 is a side elevation of the same.

Figs. 3 and 4 are transverse sectional views on the lines 3-3 and 4-4 of Fig. 2.

Fig. 5 is a plan view of the hanger frame.

b il ig. 6 is a perspective view of the hook Referring to the drawings, these show a supporting member 10 partially broken away. Any type of a supporting member that is available may be used and I have shown a portion of an I beam having flanges 11 over which a hanger clamp 12 is secured by means of bolts 13 as is well known in the art. The upper end of a threaded hanger rod 14 is fastened in the lower part of the clamp 12 by means of nuts 15.

The opposite end of the hanger rod 14 is also threaded and is inserted into an opening 16 in the hanger frame 17. A recess is provided in the upper part of the hanger frame for a threaded nut 18 and into this nut the threaded end of the hanger rod 14 is screwed. The lower part of the hanger frame extends across and over the upper flanges 19 of the rail 20. As shown in the drawings, the rail is provided with flanges 21 on the lower edge of the web of the rail which form a trackway for trolleys to pass along, the trolleys not being shown as their use is well known.

On the ends of the lower part of the hanger frame are ears 22 arranged in pairs projecting downwardly below the flanges 19 on the rail. Hook bolts 23 having a flat bearing surface 24 on the hook end of the bolt to engage the under side of the flanges 19 are positioned between each pair of ears, the threaded portion of the bolt extending upwardly through the hanger frame and having nuts 25 applied thereon to hold the frame in clamping engagement with the rail. The book end of the bolt is extended laterally on both sides of the shaft of the bolt, which provides a greater bearing surface on the flanges of the rail and also provides vertical sides 26 on the hook end which abut against the cars 22. hen weight is applied to the rail such as trolleys bearing loads passing along the rail, a downward pull will. be exerted on the flanges 19, which in turn will cause the hook end of the bolt to bear against the ears 22. The ears 22in engagement with the vertical sides 26 will prevent the shaft of the bolt 23 from becoming bent when heavy loads are applied on the rail, thereby eliminating the bending movementof the hook bolts 23.

The hanger frame 17 may be made of any suitable material, and I employ amalleable casting of suflicient length to span the upper flanges of the rail. The same bolt-s may be used with hanger frames of different lengths, and the number of pairs of ears 22 on the hanger frame may be increased when a hanger of greater carrying capacity is desired.

The recess in the hanger frame is provided quired for the connection to thehanger rod,

thereby enabling it to be used to great advantage when a. small amount of head room is available. bodiment of my invention, yet it is to be understood that various modifications thereof can be made without departing from the spirit and scope of the invention and the appended claims.

Having described the invention, what is claimedand is'desired to secure by Letters Patent therefore is:

"1. In hangers 'for'rails, the combination with a. supporting memberand a flanged rail to be supported thereby, of a hanger member secured at one end to the supporting member, a frame secured'to the opposite end of the hanger member, hook bolts connecting the frameto the flanged rail'and means associated with the frame whereby the bending moment of the hook bolts is eliminated.

2. In hangers for'rails, the combination with a support and a flanged rail to be supported thereby, of a hanger member secured at one end to the supporting member, a frame secured to the opposite end of the hanger member provided with ears extending downwardly below the flanges on the rails, and hook bolts connecting the. frame to the flanged rail in clamping engagement having laterally extended hook ends to engage the flanges on the rail and abut against the ears on the frame.

3. In hangers for rails, the combination with a supporting member and a flanged rail to be supported thereby, of a hanger member secured at one end to the supporting member, a frame secured to the opposite end of the hanger member provided with pairs of ears extending downwardly below the flanges on the rail, and hook bolts connecting the frame to the flanged rail in clamping engagement having laterally extended hook ends to engage the flanges on the rails and abutagainst the ears on the frame.

4. In hangers for rails, the'combination with a, supporting member and a flanged rail to be supported thereby, of a hanger member secured at one end to the supporting 1ne1n ber, a frame secured to the opposite end of the hanger member provided with ears extendi11 downwardly below the flanges on the rail, and hookbolts supported from the frame having hook ends extended laterally from the shafts of the bolts to engage the flanges of the rail, said hook ends having a vertical side I have described but one emadapted to abut against the ears on the frame, whereby the bending moment of the bolts is eliminated.

5. In hangers for rails, the combination with a. support and a flanged rail to be supported thereby, of a frame provided with ears extending below the flanges of the rail, hook bolts having threaded ends adapted to extend through openings in theframeand having laterally extended'hook ends to engage the flanges on the rail and abut against the ears on the frame, nuts applied to the threaded ends of the bolts to hold the frame in clamping, engagement with the rail, and means for suspending the frame from the support.

In witness whereof, I have hereunto subscribedmy name.
